GUMMED PAPER AND PROCESS OF MAKING THE SAME.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed February 23, 1907. Serial No. 358,877.

as gummed clot or stay papers for paper box making, and consists of anew or improved process for producing slight indentations, incisions,minute recesses or roughnesses over the entire surface of the gum,

mucila e or like adhesive material applied tov the sur ace of the paperto break up the surface tension of the gum. By this method of treatmentthe following advantages are obtained. The roughened surface causes thepaper to adhere more firmly to any smooth or Gum apers or the like sotreated are more easily fiidto lithogra hic or other printing machinesowing to t e air cushion provided by'the numerous indentations,obviating the usual tendency of suchto adhere to one another, and theliability of setting off after'printing is also minimized, and for thesame reason there is less liability to stick together when the gummed paor is subyected to the action of damp.

ound that gum aper so treated lies flatter in the sheet and fias not thesame tendency to curl up as is usually the case with untreated gum paers, particularly when in the form of um tic ets. Also stay papers andcloths suc as are used for edgings in paper box making are rendered moresoft and pliable and therefore more easily applied.

In order that m invention may be propave hereunto appended adiagrammatic drawing illustratmg one method and means for carrying theprocess into effect or practice.

In carrying into practice the improvements of this invention the gumpaper in ths or it may be in the form of fashioned artic es is assedunder pressure between a pair of rol ers, one of which is etched orengraved with a suitable design, or it is acted on by a similarlyengraved plate in a ress.

hen rollers are employed one of them is plain and the other is engravedor etched with a suitable design and acts on the t is also gummed sideof the paper, cloths or the like.

The gummed side of the paper is in contact with the plain roller and 18therefore not affected by the design on the other roller to any apreciable extent.

t is obvious that various arrangements of rollers may be 'em iloyed toproduce the desired effect, but the diagrammatic drawing hereto appendedillustrates one convenient arrangement. In this arrangement the dry gumpaper a passes from the roller 6, suitably mounted, between theengraved, etched or embossing metal or other roller 0 and therollerd,.half round it and the next roller e. The rollers d and e may be pa errollers or be of any equivalent or suita le materials. The pa er thenpasses between the paper or like rol er e and the plain steel or othermetal roller f and again between the paper or like roller 9 and anotherplain steel roller h whence it. passes to the roller i. In assingbetween the rollers e and f, and 9 ant h, the plain or ungummed side ofthe paper is acted on by the plain metal roller to smooth it and at sametime flatten any slight markings of the engraved roller 0 which ma passthrough to the ungummed surface of t e paper.

When a press is employed an en aved plate acts on the gummed surfacewhile the ungummed surface of the paper lies on a smooth platen, theplate being formed to suit the articles being operated on which may besheets, envelope, or other fashioned articles of gum paper or cloth.

The roller or plate may be engraved or etched with a design consistin ofnumerous crossed lines at very slight distances apart but any suitabledesi n of such a sharp indented nature-as wil produce the desired effectma be employed.

What claim as m invention, and desire to secure by Letters atent is 1.The herein described process of treating gummed paper which consists insub] ecting-the same to pressure between a smooth surface and a sharplyengraved surface, the gummed face of the aper being adjacent to thelatter, whereby t e gum on said surface is correspondingly roughened andits surface tension thereby eliminated, substantially as dcscriber l.

2.'The herein described process of treating gummed paper which consistsin subjecting the same to pressure between a smooth surface and asharply engraved surface, the

gummed face of the aper being adjacent to gum roughened to eliminate thesurface ten- 10 the latter, whereby t e gum on said surface sionthereof, substantially as described. is corres ondinglv roughened andits surface In testimony whereof I have signed my tension t erebyeliminated, and subsequently name to this specification, in the presenceof 5 calendering the paper to remove any resulttwo subscribingwitnesses.

ing marks upon the ungummed surface of the RICHARD ALEXANDER MCLAURIN,paper, substantially as described. Witnesses:

3. As a new article of manufacture, R. C. THOMSON, gummed paper havingthe surface of the T. B. BROWNLIE.

It is hereby certified that in Letters Patent No. 890,570, granted June9, 1908, upon the application of Richard Alexander McLanrin, ofMillikenpark, Scotland, for an improvement in Gummed Paper and Processesof Making the Same, an error appears in the printed specificationrequiring correction, as follows: In line 57, page 1, the word gummedshould read ungummed; and that the said Letters Patent should be readwith this correction therein that the same may conform to the record ofthe case in the Patent Oflice.
